Panniru Thirumurai (“the App”) is a reader for the twelve canonical books of Tamil Saiva devotional poetry. This policy explains how the app and this website handle information. In short, the publisher runs no server, holds no account of you, and receives none of your reading. Your text, your place in it and your preferences stay on your device. The iOS app is supported by third-party advertising, and that advertising collects a device identifier, advertising and interaction data, performance data and your approximate location, and uses them to track you across other companies’ apps and websites. What it collects is set out in full below. None of it reaches the publisher. This website carries no advertising at all.
Summary
iOSWeb- The publisher collects and stores no personal data on any server of its own.
- The text of the twelve Thirumurai is bundled with the app and readable without a connection.
- Your reading data and preferences are stored on your own device.
- The iOS app shows third-party advertising, which collects and tracks as set out below. You can turn the tracking part of it off, and the section says how.
- This website is a static page with no advertising, no accounts, and no tracking of any kind.
- iCloud sync, where enabled, runs on your own Apple Account and the publisher cannot see it.
- The tip jar and the ad-free unlock are handled entirely by Apple; the publisher never sees your payment details.
- Notifications, where enabled, are scheduled locally on your device.
Advertising
iOSThis is the declaration made to the App Store, in Apple’s own categories. Tracking has the meaning Apple gives it: linking this data with data from other companies for targeted advertising or advertising measurement, or sharing it with a data broker.
| Data type | Purpose | Linked to you | Used for tracking |
|---|---|---|---|
| Identifiers → Device ID | Third-party advertising | No | Yes |
| Usage Data → Advertising Data | Third-party advertising | No | Yes |
| Usage Data → Product Interaction | Third-party advertising, Analytics | No | Yes |
| Diagnostics → Crash Data | App functionality, Analytics | No | No |
| Diagnostics → Performance Data | Analytics, Third-party advertising | No | Yes |
| Location → Coarse Location | Third-party advertising | No | Yes |
- “Not linked to you” means none of it is joined to your name, your email or an account: the publisher has no account to join it to. It is still tied to your device, which is what makes the tracking possible.
- Coarse location is approximate — a general area, derived from the network you are on rather than from GPS. The app never requests precise location and cannot read it.
- Crash data is the one row that is not used for advertising. It is how a crash gets fixed.
This website is not covered by any of the above. It serves no advertising and embeds no advertising or analytics SDK of any kind.
Turning the tracking off
iOS- The app must ask before it may track you, and it does. If you decline, it cannot read your device’s advertising identifier and cannot track you. To change your answer later: Settings → Privacy & Security → Tracking.
- Google’s own controls for the advertising it shows you live at myadcenter.google.com.
- Buying the ad-free unlock, or leaving a tip, removes the advertising from the app entirely — see “In-app purchases” below.
Some laws, California’s in particular, treat sharing data for cross-context behavioural advertising as a sale of personal information. On that definition the advertising in this app is a sale, and the controls above are how you opt out of it. The publisher does not sell data in any other sense: it has none to sell.
Information stored on your device
iOSWeb- Reading data — your current reading position, bookmarks, recently viewed sections, and any collections you create.
- Preferences — chosen script and language, reading font, accent colour, appearance, and text size.
- Pilgrimage records — which of the temples named in Thevaram you have marked as visited.
- Supporter status — whether you have left a tip or bought the ad-free unlock, so the app knows not to show ads or ask again.
- Reminder settings — whether daily reminders are enabled, and the times you chose.
This website is a static page and stores nothing about you. It sets no cookies and reads no personal data. A service worker may cache the site’s own files — fonts, images, the page itself — in your browser so it loads offline; that is a copy of the site, not anything about you, and is readable only by this site in that browser.
Cloud sync (optional)
iOSSigning in (optional)
iOSIn-app purchases
iOS- Nothing in the app is gated behind a purchase. Every verse is free whether or not you ever tip.
- If you opt in to share sales and financial reports, the publisher receives only aggregated figures through App Store Connect — never your identity or payment method.
Apple Music (optional)
iOSNotifications (optional)
iOSServers and network requests
iOSWeb- iOS: the app operates without a publisher backend and makes no network requests to the publisher. It does call Google’s advertising servers to fetch ads, as described above, and Apple’s servers for iCloud sync, Sign in with Apple and Apple Music, each under Apple’s own policies.
- Web: this site is served by ordinary web hosting, which — like any web host — records standard request logs, including IP addresses, for delivery and security. This is inherent to being a website rather than an installed app.
Information the app does not collect
iOSWeb- Your name, email address, contacts, photos or files.
- Precise location. Only the coarse location described above, and only via the advertising SDK.
- The content of your reading — the verses you open or bookmark, your place in the text, and what you type into search. These stay on your device and are sent to no one, including the publisher.
- Apple Music listening history, or your credentials with it.
The distinction is worth stating exactly, because the section above complicates it. The advertising SDK records product interaction — that the app was opened, that a screen was shown, that an ad was seen or tapped. It does not receive the text you are reading or the terms you searched for, and neither does the publisher.
Information platform owners may receive
iOS- Apple may process device metadata, download metrics and diagnostic crash logs, under its own privacy policy.
- If you opt in to share diagnostics, the publisher receives only aggregated, anonymised crash reports and basic usage statistics through App Store Connect. That data is decoupled from your identity.

iOSWebRetention and deletion
iOSWeb- Local data (app): uninstalling removes all local data from your device immediately.
- Local data (web): clearing this site’s data in your browser removes its offline cache. There is nothing else of yours to remove.
- Synced cloud data: disable iCloud sync in the app’s Settings, or delete the app’s iCloud data through iOS Settings under your Apple Account.
- Sign-out: signing out in Settings removes the sign-in from that device.
- Advertising data: it is held by Google, not the publisher, so it is Google that deletes it — reset or delete the advertising identifier in your device settings, and use myadcenter.google.com for the rest.
